We installed ClosetPilot and tried all the features. Compared to ClosetPilot's sharing and follow features, PoshMarvel allows you to target buyers and acquire followers more efficiently.
ClosetPilot is a browser extension. We were able to install and register without any problems. It has all of the standard features, share, follow, like, offer, bulk price editor, activity returner etc. Sharing and following works from any page is great. There is no notable feature that is specific to ClosetPilot. There are two plans, a free forever plan (100 shares per day limit) and $29.99 per month.
When a CAPTCHA occurs, it notifies the user. User can pay for an account with 2Captcha to pay automatically solving. We didn't see any problems with sharing and following, it works as expected. The progress screen stays at the center and shows all activities. However, these features are very limited in getting you new followers. It expects you to know which closets to follow, which searches to run etc. In addition, the extension stays on the page, lower left, it is very easy to interact with.
